Title: Tacho
Post by: Bitzer! on April 27, 2008, 05:06:00 pm

Ok I'm guessing you guys use Tacho I use rev counter? I'm looking to swap out the monster fuel guage and insert a rev counter. The main question is most of the cars over here have an independant coil pack where I can take a feed from. Where do I start on my '79?

cheers as always

ps - I have looked thru older topics before posting, honest!!

The tach connection is on the cap of an HEI.

High Energy Ignition. Right on the side of the cap there is a spot to plug a tach in.

If you've got the stock-type HEI it will be a spade-lug under the coil cover right next to the 12V lead ;D
